Cannot get the "Expected a root view controller" problem resolved

I cannot get the "Application windows are expected to have a root view controller at the end of the application launch" error resolved from the 'Build a self-destructing Message iPhone app' tutorial that is discussed towards the end of video: http://teamtreehouse.com/library/build-a-selfdestructing-message-iphone-app-2/designing-and-starting-the-app/a-storyboard-with-a-tab-bar-controller.

Removing the following lines of code from the didFinishLaunchingWithOptions method in the AppDelegate.m doesn't solve the problem: self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; self.window.backgroundColor = [UIColor whiteColor]; [self.window makeKeyAndVisible];

Running the simulator after removing these lines of code makes the simulator go black. I am currently using Xcode 5. Can somebody help me resolve this problem?

Can you post all the code for your entire didFinishLaunchingWithOptions method?

did you leave return YES; in that method? did you set your storyboard as the main storyboard of your app?

@Stone: I figured the solution to the problem. You are almost right with the storyboard setting. While Xcode 5 doesn't have the option to set the "main storyboard", setting the 'Main Interface' to my storyboard solved the problem. Thank you the suggestion.
